Title:
PROCESS CARTRIDGE
Document Type and Number:
WIPO Patent Application WO/2022/270241
Kind Code:
A1
Abstract:
Provided is technology which can reduce an operational load on a user when installing a memory in a developing cartridge and a drum cartridge, and attaching, to an image forming device, the drum cartridge having the developing cartridge attached thereto. The drum cartridge has a first memory 71 having a first electrical contact surface 711, and a first holder 72 that holds the first electrical contact surface 711 so as to be movable relative to a drum frame. The developing cartridge has a second memory 81 having a second electrical contact surface 811, and a second holder 82 that holds the second electrical contact surface 811 so as to be movable relative to the housing. A plate 200 connects the first holder 72 and the second holder 82 in a state in which the developing cartridge is attached to the drum frame. The second holder 82 moves together with the plate 200 in conjunction with movement of the first holder 72. This makes it unnecessary for the second holder 82 to have an elastic member, and thus can decrease the operational load on the user.
